Hi all I would like to thank the contributors on this site for the valuable information and the help I have received I have fixed several monitors from the info you guys have given and mostly was replacing bad caps. I will continue to use this site, keep up the good work. Here is one I can`t seem to find I am checking out a lcd monitor for a friend. It is a e-Machine brand. When I plug it in and fire it up the light is green than it shows a no signal on the screen than goes black and the light goes amber. The monitor cable is properly attached and working ok on another monitor that I have tried so it is not the video card on the pc. What should I look for inside the monitor. Would this be on the video board or the inverter board. All cabs seem good.

Re: e-machine no signal
I had a similar problem with an eMachines E15t3G. It was one (well, three...) bad wires inside the VGA/Signal cable. Check those with a multimeter. If they are OK, then the problem will be in the Video Board.

Re: e-machine no signal
Thanks eguevarae I changed out the cable and still the same. I will check out the board. Is there something common on the board that could cause this problem? What do I look out for?Originally posted by eguevaraeComment

Did you solve this? I have received a dead eMachines e15t3g. Is this the same model as yours?There are 10 kind of people in this world: those that understand binary, and those who don't.- ASUS ROG Maximus IX Code

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM -
Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

Things I tried
- Bought a new AC adapter thinking that was the problem but the problem... -
Samsung synchmaster 226BW.
Before I replaced 5 caps, the screen was dim.
Sometimes it wouldn't turn on.
I opened it up, and found 4 bad caps in the pwr supply section.
I unfortunately installee one backwards, i.e. wrong polarity.
When I turned it on, I head a loud pop, and I quickly shut it off.
The replaced caps are 3 860uF 25V's, and 1 330u 35V.
One of the 860uF blew.
I didn't have another 860uF at home, so I tried it with a 1000uF 35V cap (I remember the reading of the 1k uF cap was close...
